  1. 1. Extremal Mechanisms for Pointwise Maximal Leakage

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Leonhard Grosse; [2023]
    Keywords : Privacy; mechanism design; information leakage; convex optimization; information-theoretic utility; Integritet; Mekanismdesign; informationsläckage; konvex optimering; informationsteoretisk användbarhet.;

    Abstract : In order to implement privacy preservation for individuals, systems need to utilize privacy mechanisms that privatize sensitive data by randomization. The goal of privacy mechanism design is to find optimal tradeoffs between maximizing the utility of the privatized data while providing a strict sense of privacy defined by a chosen privacy measure.

  3. 2. Underwater probe for deep sea exploration : Long range acoustic underwater communication system

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Kim Nykvist; [2020]
    Keywords : Acoustic communication; temperature; Expendable Bathythermograph; XBT;

    Abstract : This was a thesis that was commissioned by Researcher Peter Sigray at the Royal Institute of Technology (KTH) in Stockholm and was based on an idea by Professor Thomas Rossby, University of Rhode Island (URI). The idea was to further develop the existing Expendable Bathythermograph (XBT), which has been in use since the 1960s. READ MORE

  4. 3. Evaluation, adaption and implementations of Perfectly Matched Layers in COMSOL Multiphysics

    University essay from KTH/Numerisk analys, NA

    Author : Simon Erlandsson; [2020]
    Keywords : Applied mathematics; computational mathematics; finite element method; FEM; perfectly matched layer; PML; COMSOL; Tillämpad matematik; beräkningsteknik; finita elementmetoden; FEM; PML; COMSOL;

    Abstract : Perfectly matched layer (PML) is a commonly used method of absorbing waves at a computational boundary for partial differential equation (PDE) problems. In this thesis, methods for improving the usability of implementations in Comsol Multiphysics is addressed. READ MORE

  5. 4. Dynamic Soil-Structure Interactionof Soil-Steel Composite Bridges : A Frequency Domain Approach Using PML Elements and Model Updating

    University essay from KTH/Bro- och stålbyggnad

    Author : DIEGO FERNANDEZ BARRERO; [2019]
    Keywords : Dynamics; soil-steel bridges; soil-structure interaction; model updating; PML; particle swarm; corrugated steel plates; frequency domain assurance criteria; parallel computing 2;

    Abstract : This master thesis covers the dynamic soil structure interaction of soil-steel culverts applyinga methodology based on the frequency domain response. At the first stage of this masterthesis, field tests were performed on one bridge using controlled excitation. READ MORE

  6. 5. Finite Element and Dynamic Stiffness Analysis of Concrete Beam-Plate Junctions

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Patrik Andersson; [2016]
    Keywords : Train-induced; vibrations; building; Finite Element Method; FEM; Dynamic Stiffness;

    Abstract : Measurements and predictions of railway-induced vibrations are becoming a necessity in today’s society where land scarcity causes buildings to be put close to railway traffic. The short distances mean an increased risk of the indoor vibration and noise disturbances experienced by residents. READ MORE
